I can find support for the two previous NEC DVD burners on their official site.
When the drive installs it`s listed as an NEC drive.
They list compatable media for the drive on their official site.
They seem to support OEM products by listing them on their official site.
If they change policy with this drive without notice they should be blasted along with the companies that sell them.
The problem in question is that they list Ritek -4X DVD media with L19 dye code as compatable and that is not true for most of us.
The firmware write stratgey is in error for this media or their 2500A drives differ slightly. Some have a compatable drives others with problems don`t.
I would think they would want to fix this or all OEM`s will be liteonit.
It appears that NEC just doesn`t care
This is my Humble Opinion.
